And for the record, I can confirm that from trunk, a saved
dolphins.svg opens OK with inkscape. The bug (as mentioned on -dev)
we're seeing is actually a Qt bug.

OK, the plot thickens. I may have spoken too fast: the behavior we
see in the Qt console is indeed the same I reported earlier, and the
MPL bug where doing pastefig() (which just calls savefig() to svg)
causes the bad redrawing of the axis is still there, and definitely a
MPL issue.
BUT, if I save the svg manually to a file from mpl or from the Qt
console, so the raw SVG data is written out, then it looks fine once I
open it in inkscape.
So it seems the problem is actually with the Qt widget's display of
that SVG file, somehow it seems the Qt widget doesn't correctly
understand the clipping info (which Inkscape is OK with).
We'll bounce this over to the Qt folks to see if it's a known bug in Qt.
In summary, only the bad redrawing of axes is a confirmed MPL issue,
sorry for the confusion.
Cheers,

Hi All,
I have been trying to make a 3D scatter plot using mplot3d and I would
like the markers to have their colour according to the Z value.
>From what I understood in the tutorial and API I have to use the cmap
and norm kwargs, but all my attempts failed.
I am trying to do it like this:
ax.scatter(x,y,z,s=10,marker='o',c=????,cmap=????,norm=????)
However I am not sure what to pass to c, cmap and norm.
Any help ?
Thanks.
Cheers,
Pedro

A crude but functional way is to just run apt-get build-dep, and then
cancel the actual download. That list is printed on screen, and one
can then manually apt-get install just a subset. I'm sure one of our
resident Debian experts can suggest a more elegant solution.
Cheers,

Nope, identical behavior, just tested with a rebuilt-from-now numpy and mpl:

It seems to be pulling in all of TeX Live, which is huge and by no means
necessary to run matplotlib. Matplotlib can pass strings through TeX for
formatting (the usetex option) but doesn't do that by default.
Oh, it's build-dep... I guess you need TeX to build the manual, but I
don't think it is needed to get the library itself working.
Is there a way to ask apt what the build dependencies for a package are,
and then install only a subset?

Actually, i must apologize
By calling fonts by their real name eg: "WenQuanYi Zen Hei" (instead 
of wqy-microhei, their file name), i can display them. So no worries 
for issue 2. However, I do not manage to export the png to pdf or eps 
due to the following error:
"TrueType font is missing table"
Is that due to my changing the font name from *.ttc to *.ttf?

benoit

Hi,
When looking in my fontFile.cache, i did not find any of 
'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf', 
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttf' or simhei. this is 
why i could not display the characters.
I deleted the cache and re-lounched my script, so that mpl had to look 
for the fonts and update the cache. It added the simhei fonts to the 
list. I can now display chinese characters with the simhei font.
I ran into 2 more issues:
- Simhei "has no glyph names", which prevents me from exporting into pdf
- I do not manage to make mpl take into account microhei and zenhei, 
whereas i have them in 
'/usr/share/fonts/truetype/wqy/wqy-microhei.ttc'. I changed their name 
to '/usr/share/fonts/truetype/wqy/wqy-microhei.ttf', and now mpl finds 
them. However they fail to display chinese characters
So, thank you for your help, i managed to display chinese characters 
but there are still some issues. Do you have any idea?

This message was sent using IMP, the Internet Messaging Program.

oh, only test it on Windows yet. both "sim hei"and "microsoft yahei"
are fontname on Windows Platform.
maybe just copy "Sim Hei" to font directory is not enough? no clue here.
I just test the script on Linux (Ubuntu 8.04, Python 2.5, matplotlib
0.98.4) with the follow steps:
1, find the configure directory of matplotlib
import matplotlib as mpl
mpl.get_configdir()
return "~/.matplotlib"
2, in the configure directory, there is a file "fontList.cache"
I find this
(dp294
...
S'WenQuanYi Zen Hei'
...
S'/usr/share/fonts/truetype/wqy/wqy-zenhei.ttf'
...
I just know WenQuanYi is a "Chinese font"
http://packages.ubuntu.com/hardy/ttf-wqy-zenhei
3, replace "Sim Hei" in your original script with "WenQuanYi Zen Hei",
now it can display Chinese.
both methods still work(embed fontname argument, or set
mpl.rcParams['font.sans-serif'])
maybe you can find a font that support Chinese character on your
platform with these steps and try again?
